This occurs with the latest SVN version:

Code: Select all

PhpString was not marked as serializable. Will be fixed in upcoming release.

[kripper]

Ok. Thanks.

I'm providing a test case:

Code: Select all

   // Doesn't work
   $test = '';
   $test .= 'ok';
   $_SESSION['test'] = $test;


Code: Select all

   // Works
   $test2 = '';
   $test2 .= 'ok';
   $test2 = '' . $test2; // Probably this converts the PhpString (not serializable) to something else (serializable)
   $_SESSION['test2'] = $test2;


Note that the serialization problem only occurs when using the ASP.NET StateHandler.
